SNAP-HOOK.

.-. '.CPICATION forming part of Letters Patent No. 388,254, dated August21, 1889.

Application filed June i', 1883. Serlal No. 215,819. (No model.)

To all wtom/ it may concern,.-

Be it known that LEVERAL BRADLEY, a citizen of the United States,residing at Trumansburg, in the county of Tompkins and Stateof New York,have invented certain new and useful Improvements in Snap-Hooks, ofwhich the following` is a specification, reference being had therein tothe accompanying drawings, in which-e Figure l represents a perspectiveview of my improved snap-hook; Fig. 2, a longitudinal sectional view ofthe same, and Fig. 3 a plan View thereof.

This invention is particularly designed as an improvement upon thatclass of snap-hooks covered by Letters Patent No. 364,572, issued to meon the 7th day of June, 1887; and it has for its objects to simplify andimprove the construction generally of such hooks, whereby they arerendered more practical and positive in operation, as will more fullyhereinafter appear.

rIhe invention will be fully understood from the following descriptionand annexed drawings; and it consists in certain novel features ofconstruction,that will be specifically pointed out :in the claimsappended.

Referring to the drawings by letters, A designates the stationary bodyportion of the hook, which is provided with a strap or chain loop, B, atits rear end and a pair of perforated ears, a a, upon its upper side.

Projecting from the forward end of the body A is the stationary hook Cand the beveled shoulder b, this hook U being inclined rearwardly at itsforward end, forming a nose, c. Pivoted between the ears a a by means ofa transverse pivot-pin, d, is the rear end of the movable hook U',corresponding in size and shape to the hook C, but oppositely inclinedat its forward end, forming the nose 0, this hook C being provided witha lateral beveled shoulder, b. As thus constructed, the beveled freeends of the hooks C G abut, respectively, against theeorrespondingly-beveled shoulders b b', and the contiguous faces of thehoops themselves lie `fiat against each other. The rear end of the hookC is provided with a short downwardly-projecting lug or extension, e,against which bears the rear end of a coil-spring, E, this spring beinginserted in a recess or cavityin the body A, and

serving to keep the hooks normally closed. The lug e fits between theears c a, and when the hooks C C' are forced apart the spring E iscompressed.

I have described the snap-hook generally as shown in my former patent,and I will now describe my improvements thereon.

In order to restrict the movement of the hook C', I provide the samenear its rear end with a lateral lug,f, which is adapted to ecntact witha shoulder,f', formed ou one of the ears a, when thehooks are forcedapart, thereby preventing the hook C from being thrown too far back whenthe snap is opened.

A difficulty with my former snap-hooi; was that the rear end of thespiral spring E would work out under the lower end of the extension e,and by the continual opening and closing of the hook this spring wouldeventually worm itself entirely out of its cavity. In order to remedythis defect, I bend the rear end of the spring in toward the center ofthe same, as shown in Fig. 2 at g. I also curve or turn up the portion gof the body between the ears a a, the degree of curvature of thisportion g being approximately equal to the arc described by the lowerend ot' the extension e when the hooks are separated. By this means therear end of the spring will be effeet-ually prevented from working outunder the lowerl end of the extension e.

'The letter 7L designates a hole to permit the ready egress of any wateror sand that may find its way into the spring-cavity.

It will be observed by reference to Figs. l and 3, particularly, thatthe free ends of the hooks C C are turned slightly outward in oppositedirections, and that the beveled shoulders b b' are correspondinglylaterally enlarged. The object in thus curving the ends of the hooks andlaterally enlarging the shoulders b b' is to facilitate the removal of aring from the snap-hook. All that is necessary to do to remove the ringis to hold the same firmly in one hand and at the same time twist orturn the snap-hook to one side. By this means the hooks are forcedapart, an d then the ring may be easily slipped out from between thehooks, the curved ends of the hooks permitting this to be done.

I also Vfind that by making the recess in which the forward end of thespring rests IOO shallowerv than in my former patent, as shown in Fig.2, the body portion A will be easier to manufacture, and a newspring canbe substituted for the old one without removing the pivot-pin d.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is'- l. The combination, with thehook-body A, providedV with a loop, B, and forwardly-extending hook C,and beveled shoulders b, of the spring-aetuated hook C', provided with ashoulder, b', the free ends of the said hooks C C being curved outwardlyin opposite directions, and the shoulders Z1 Z1' being correspondinglylaterally enlarged, substantially as herein set forth.

2. The combination, with the hook-body A, provided with perforated earsct a, a loop, B, and vforwardlyprojecting hook C, and beveled shoulderb, one of the said ears a being provided With a shoulder, f, of amovablehook, C', provided with a lateral beveled shoulder, b', and 1a downwardextension, e', this portion C being pivoted between the said perforatedears a, a, and also provided with a lateral'lug, f, and a spiral springinserted in a cavity in the body A and adapted to bear against the saidextension e and hold the hooks closed, substantially as described.

3. The combination, with the body A, provided vvith a loop, B, and ahook, C, and a pair of perforated ears, a a, and a slightlycurvedportion, g', between these ears, of a movable hook, C', pivoted betweenthe said ears a a and provided with a downward eX- tension, e, and aspiral spring, E, inserted in a cavity in the body A, and adapted tOpress with its rear end upon the said extension e and hold the Vhooksnormally closed, the rear end of the said spring being turned in towardits center, as at g, substantially as described.

In testimony whereof I affix my signature in presence Of two witnesses.
